Question

write the coordinates of the vertices after a translation 1 unit up.

Explanation:

Step1: Find original coordinates

From the graph, original coordinates are \( R(1,-7) \), \( S(2,-7) \), \( T(0,-4) \).

Step2: Apply translation rule

Translation 1 unit up means add 1 to \( y - coordinate \).
For \( R(1,-7) \): \( y=-7 + 1=-6 \), new coordinate \( (1,-6) \).
For \( S(2,-7) \): \( y=-7 + 1=-6 \), new coordinate \( (2,-6) \).
For \( T(0,-4) \): \( y=-4 + 1=-3 \), new coordinate \( (0,-3) \).

Answer:

\( R(1,-6) \), \( S(2,-6) \), \( T(0,-3) \)
